Composite image of the grey framed central area + near- and far-ultraviolet (NUV, FUV) data from the GALEX satellite telescope. FUV-bright sources appear blue/white, NUV-bright sources appear yellow. The FUV data reveals star forming regions in a ring around the central structure of NGC 404 which is not visible in the optical image. The central structure is NUV-bright which indicates that it is dominated by older stars.

NUV/FUV data taken from: D. A. Thilker et al., The Astrophysical Journal Letters, 714:L171–L175, 2010 May 1
